MINE om Application lcd October 25, 1921.

To all whom it may concern:

lBe it known that I, CARL SGHoLz, a c1t1zen lof the United States, residing at Charlesof the objects of the invention is to provide a composite body construction, that'is, one

in which a portion is "made of structural iron, while the remainder is made of wooden planking. The chief objection to all steel cars vare their rigidity and liability to take :a permanent set, 1f once bent out of shape. On

. `the other hand, a wooden car is much more ilexible,'and will give to compensate for. unevenness'in the track, but deteriorates much more rapidly than a steel car. In a car of the composite construction, many of the desirable oints of both wood and steel can be emb ied.

Another object of the invention is the construction of an underframe comprisin channel irons so arranged that the oorio the car is continuous and extends beyond the ends of the car bod to serve as bumpers.

A further object ko the invention is to provide 'a car having an increased capacity and at the same time keeping its height and center of avity low.

With these general objects in view, the invention consists in certain novel and pecu liar features of construction and combination of partsas hereinafter described and claimed; and in order that'it may be fully understood reference is to be had to the accompanying drawings, in which similar re ference characters indicate corresponding parts in all the views.

Fig. 1 is a plan view of the car;

Fig. -2 is an elevation and fragmentary section;

Fig. 3 is a section on the line 3 3 of Fig. 1, and i Fig. 4 is a detail view.

Referring to the--drawings for a further disclosure of the invention, 1 is Ithe floor of thecar constructed of wooden planks running lengthwise thereof. The inside planks 2, 3 and 4 are extended beyond the ends of the car body to provide bumpers, `the ends of which are cut to provide a curved 'sur face, which is protected a ainst wear by the metal` armor plate 5. einiorcing the serial No. 510,321.

Hoor extensions are supplementary wooden pieces 5a secured thereto.

Running transversely of the car at each end and supported on'the floor are channel irons 6. side of the car and secured to the under side of the bottom is a steel plate 7, which projects'sidewise beyond the bottom to provide steps 8 on which rest the channel irons 9. J The depth of the channel irons 9 is suf ficlently greater than the depth of the channel iron 6 so that the u per surfaces are all in the same plane.m Iitigidly secured to the channel iron underframe, is l1a series of vertical angle irons 11, connected together at their upper ends by the horizontal angle irons 12', the corner angle irons at their lower ends being secured respectively `to .a transverse and longitudinal channel iron for holding the same -in rigid relationship;'as particularly shown in Fig. 4.

Supported by the channel irons 6 and 9 and rigidly secured tothe angle ironsl A12 are the wooden'side and end planks 13.

Secured to the bracing plate 7 are roller bearing journaled boxes 15a for supporting the wheels 14 and axles 15. The floor of the car is cut away to provide openings' 16 for the wheels, these openings being covered by hoods 17 secured to the inner side of the bottom of the car.

AFor bracing the car transversely, intermediate the ends, there are provided a series of angle irons 24 secured to the bottom; and at each end, there is a transl verse plate 23.A Brackets 18 are secured to the inner side of the car body for also. bracing it.

Running longitudinally of eachv The draft gear at the end of the car is 915'4 covered by a housing19 and comprises a draw 'bar 20, and an abutment 21, with a spring 22A interposed therebetween to resiliently take up the shocks incident to starting the train of cars.

I-have referred herein to the underframe constuctin as comprising channel irons, but

any of the other well known equivalent structural shapes could be substituted there- ,for without departing from the spirit of the invention.

From the above description it willbe apparent that I have 'produced a device of the character' described, which possesses all the features enumereted es desirable, and While FI have illustrated and ydescribed the preferred form of the invention, it will be understood that I reserve the right to all changes properly falling within the scope and spirit of the appended claims. p

Therefore what I claim as new and desire secureby Letters Patent is; .l

" 1. A mine car body having an under- .frame construction'comprising horizontal channel irons, a oorinterposed therebetween, the said irons extending a substantial distance above the level of` the floor, the

,dat side of the channels being on the inside 'i the body.

2. A mine car body having an underframe construction comprising horizontal channel irons, a wooden floor interposed therebemembers, a floor interposed therebetween,

l vertical irons securedvto'the said members and a Wooden superstructure supported on the said members in the same plane therewith and secured to the outer side' ofthe y said last named irons.

'v l members,

- members, a wooden floor interposed between the side members and extending beyond the transverse members tojprovide'end bumpers, the saidtransverse members resting on the floor. v

5. A mine car body having an underframe construction of structural ironmembers, a wooden ioor inter osed between the said members and'rein orcing plates extending longitudinally of the bottom alongthe sides. 6. A mine car body having an underframe construction of structuraliron members, ka

Wooden floor inte osed between the said lmembers and rein orcing plates extending longitudinally of the bottom along the sides v` and axle boxes secured to the said plates.

7. Amine car body having an underframe' construction comprising side and end channel irons, the flat side of the channels being on the inside of the body, vertical -an le. irons secured to the said channel ironsor supporting the sides of the'body, the #corner an le irons being secured to the Bat sides of a side and end channel respectively for 'holding the same in fixed relationship. 'l

8. A mine car body having an underjram plates extending beyond the end of construction comprising side and end niembers, the end members being of less depth` than the side members, the upper surface of the side. and end members being in the same plane.
